The 1st Executive Council of the Irish Free State (6 December 1922 – 19 September 1923) was formed by Pro-Treaty faction of Sinn Féin, which later became the Cumann na nGaedheal party.[1] The Constitution of the Irish Free State came into force in December 1922 and under its terms the Second Provisional Government was replaced by the Executive Council.

However elections were not held for the 4th Dáil until August 1923 and so the membership of the 1st Executive Council closely reflected that of the Second Provisional Government of Southern Ireland that had preceded it. The 1st Executive Council was replaced by the 2nd Executive Council shortly after the 1923 general election.
